WASHINGI-MACHINEGEAR.

SPECIFICATION forming part of Letters Patent No; 252,416, dated January17, 18E2.

Application filed October 31,1881.

To all whom it may concern Be it known that I, OBED W. BARNARD, ofHarlan, in the county of Shelby and State of Iowa, have invented certainnew and useful Improvements iuWashing-Machine Gear; and ldo herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to whichitappertains to make and use the'same,

reference being had to the accompanying drawings, which form a part ofthis specification, and in which- Figure 1 is a face view of thedrive-wheel of myimproved gear for washingmachines. Fig. 2 is alongitudinal central section of the same, and Fig. 3 is a side elevationof the top part of so much of an agitator washing-machineas is necessaryto illustrate the application and operation of my invention.

Similar letters of'reference indicate corresponding parts in all thefigures.

My invention has relation to the mechanism for operating so-calledagitator? washingmachiues; and it consists in the detailed constructionand arrangement of the 'drivewheel with a double set of cogs and twobearings arranged-oneabove the other for regulating the stroke of thewheel, substantially as hereinafter'tniore fully described, andparticularly pointed out in the claims.

In the annexed drawings, A represents the circular disk or body of thedrive-wheel, which is cast in one piece with two parallel uprights,

a a, united by a crossbar, b, on top, which.

forms the handle.

The circumference of the diskA is cast with inwardly-projectingtriangular cogs or teeth 0, and has a central bearing, B, above which isanother bearing, 0. y

1) represents an auxiliary set of cogs, of the same shape andconstruction as the cogs c of the main wheel, the body of which is castwith two inwardly-projecting lugs or cars, E E. The

set of cogs D, with its ears E, is a separate casting, which is secureddetachably upon the face of the disk A by bolts 00, inserted through theears E E and coinciding bolt-holes in the face of the disk, so placed orarranged that the casting Dwitl have the upper bearingiU, of disk A asits center. In other words, the sets of cogs c and D are not concentricwith one another, the former having as its center the cen- (No model.)

tral bearing, B, of disk A, and the latter the bearing 0.

F is the pinion of the rotary reciprocating agitator-shaft G, which isadapted to engage with either one of the two sets of cogs. As thedetachable inner set, D, of these projects some distance in over theface of disk A, the latteris made adjustable upon the center-pin orfulcrum H laterally, so as to bring either one of the two sets of cogs cor D to mesh with the pinion F.

From the foregoing it will be seen that the disk or drive-wheel A maybeshifted upon its fulcrum H and adjusted so as to bring either oneofthe two sets of cogs into play, thus regulating the length of thestroke of the agitator, and, of course, the power necessary foroperating it. In washing bed-quilts, carpets, or other heavy materialthe stroke is shortened by inserting the fulcrum bolt H through theupper bearing, 0, and bringing the inner or auxiliary set of cogs, D,into play, while the bearing B and cogs c are brought into play inwashing w caring apparel or other arrticlesota character to be handledeasily. v

Having thus described my invention, I claim and desire to securebyLetters Patent of the United States- I 1. The drive-wheel A,cast withthe inwardly-projecting cogs c and handle aa b, and having a centralbearing, B, and auxiliary hearing G, and auxiliary set of cogs D, castwith ears E E for their attachment to the face of disk A, concentricwith the upper or auxiliary bearing,-O, substantially as and for thepurpose herein shown and described.

2. The combination, with the pinion F of a washingmachine agitator, ofthe vertically and horizontally adjustable drivewheel A,
